Evidence over claims

Can a frequency label tell you what a track does?

The 92% finding, its source and Biotune’s approach to sound design.

The Biotune philosophy

Biotune is not your average meditation app.

We don’t build programs around Solfeggio promises or claims that one frequency delivers one guaranteed result. We focus on how sound is delivered, how it moves through the body, and how people respond.

92%of popular “healing frequency” tracks did not contain the advertised frequency.

A 2026 spectrum analysis of 150 streaming tracks labeled 528 Hz or 432 Hz found that 92% lacked the advertised frequency and 86% were slow ambient music (Yuvacı, 2026).

Read the study

Physics, not magic numbers.

Resonance describes how a system responds to vibration. It is not a promise that a named frequency heals a condition.

A protocol, not a trend.

Artists follow a protocol. Brainwave states and nervous-system regulation guide the design, with BodyWaves adding sound you can feel on compatible equipment.

Test. Listen. Refine.

Biofeedback informs Tuning and Pro. Pilots and clinical practice inform Clinical. Seven years of experience shape the work, not a guarantee of individual results.

What about Solfeggio frequencies?

The fixed Solfeggio frequency list was created in the 1990s through numerology, not derived from medieval chant or physics. The Schumann resonance is a 7.83 Hz electromagnetic phenomenon, not an audible tone your music can align with. And because resonance depends on mass and stiffness, no single frequency resonates the same organ in every body. Some studies do measure real responses to particular tunings, such as a lower heart rate with 432 Hz music. That is psychoacoustics, not a miracle number. We design for brainwave states and nervous-system regulation, then test the response.
